H11.2 At a sudden contraction in a pipe the diameter changes from Dito D2. The pressure drop, Ap, which develops across the contraction is a function of D, and D2, as well as the velocity, V, in the larger pipe, and the fluid density, P, and viscosity, u. a) Why shouldn't you choose both D, and D2 as repeating variables? b) Use D, V, and u as repeating variables to determine a suitable set of dimensionless parameters using the Buckingham...

An impeller is a rotor used to increase the pressure and flow of a fluid. For an isolated rotating impeller the required torque, T can be described by diameter of impeller D, density of fluid p, dynamic viscosity of the fluid u and angular velocity of the impeller w. By using Buckingham Pi Theorem (dimensional groups theorem), determine the dimensionless relationship between Torque and other parameters. Show that nondimensional parameters that you find. NOTE: Use a length, a density...

June 1. Consider steady, fully-developed laminar flow of air through a Laminar Flow Element (LFE, a type of flow-meter) with an aligned bundle of 100 small bore tubes, each of diameter D 2.00 mm, and length L 200.0 mm. The pressure drop per unit length (Ap/L) across each of the 100 tubes is a function of the tube diameter D, fuid viscosity u (in units N s/m2), and average air velocity Vave....

4. An incompressible fluid with viscosity u and density p was contained in pipe of length L and radius R. Initially the fluid is in rest. At t=0, a pressure difference of AP is applied across the pipe length which induces the fluid flow in axial direction (V2) Only varies with time (t) and pipe radius (r). There is no effect of gravity. To describe the fluid flow characteristics, after the pressure gradient is applied, answer the following questions: a)...
